• AudioQuest Earth RCA Interconnect Pair (1.5 m) – A flagship analog interconnect designed for advanced hi-fi systems; features Triple-Balanced geometry and heavy shielding to maintain pristine signal reference.
• Ultra-premium conductor and insulation technology – Utilizes Perfect-Surface Copper+ (PSC+), FEP Air-Tube insulation, and a six-layer carbon-based Noise-Dissipation System (NDS), resulting in lower distortion and broader micro-dynamic retrieval.
• Ground-reference isolation and Dielectric-Bias (DBS) support – The Earth cable includes a separate ground-reference conductor so the shield is not used as the signal return, reducing ground-plane modulation and improving staging.
• System-upgrade refinement – Reviewers cite the AudioQuest Earth RCA’s noticeably quieter background, enhanced imaging depth and increased detail in complex passages when substituted for lesser interconnects in revealing systems.
• Product length 1.5 m per pair – This standard length supports typical high-end setups while maintaining the benefits of optimized conductor geometry and insulation for minimal signal degradation over moderate runs.
• Premium build and terminations – Features cold-welded, silver-plated copper plugs over high-purity red copper, ensuring exceptional connector integrity and continuity for demanding signal paths.

Founded in 1980 by Bill Low in Irvine, California, AudioQuest traces its roots to 1978, when Low, a hi-fi store manager and avid enthusiast, began crafting superior audio cables to overcome the signal degradation he observed in existing products. Dissatisfied with subpar materials and construction, he prioritized advanced conductors like 6N copper, innovative insulation, and precise geometries, quickly earning acclaim after demos at events like the 1979 Summer CES. This passion-driven origin propelled AudioQuest from a cable innovator—first U.S. company to advance signal transmission in 1985—to a global force in high-performance audio.
While renowned for its expansive lineup of analog, digital, and AC power cables, including HDMI for video, AudioQuest has broadened into USB DACs and headphone amps, highlighted by the multi-award-winning DragonFly series launched in 2012. The brand also offers Niagara and PowerQuest power conditioners, alongside custom-install solutions, all engineered to maximize system fidelity without venturing into amplifiers, speakers, or turntables.
AudioQuest commands a premium position in the high-end market, supplying thousands of specialist retailers across 60 countries as the dominant cable provider for discerning audiophiles. Its relentless innovation, from conductor purity to dielectric design, delivers tangible performance gains, cementing a reputation for value and musicality that serious hi-fi buyers trust.
